'ro ALL WHOM 1T MAY coNcERN:

Be it known that I, JMES M. CROGKETT, of Newbel'n, of the ccunty'ot`Pulaski, and Stute of Virginia., have.

invented a new and useful iMode of Ventilating Chimneys to dwelling andother houses called the Chimney- Ventilator endl do hereby declarel thefollowing to be a. full and exact descriptionthereof', reference beinghad to the accompanying drawings, und to the letters of reference markedthereon, making a. part of this specification.

The nature of my invention consists in the arrangement and constructionof the box, damper, lid, and pipe, for the purpose of furnishing anair-passage from the nearest point outside of the house, to a. pointimme- ..diately `in front of the iir'e, by means of the pipe passingfrom said point outside of the house, and under the hearth, and thenconnecting witha receiving and ,distributing-box, that passes upwardthrough the hearth at the point in front of the fire.

This invention prevents all chimneys from smoking, that would otherwisedo so from want of sufficient ventilation, and else relieves the roomfrom all unpleasant droughts of cold air, and unpleasant sounds producedb v the air passing through the doors andwindows, and alsogreatlyfacilita-tes the -kindling of the fire, as well as the warming of theroom. i

Figure 1 represents a front view of the ventilator.

Figure 2 a side elevation.

The receiving and distributing-box A, as shown on the dra-wing, projectsan inch above the hearth, and on the front towards the fire-placecontains a number of apertures, B B, proportionate to its length, and issupplied with u damper, C, regulating the supply of air that may befound necessary. The said box A should be about four inches widehytwelve inches long, and should pass three inches cr more below the topof the hearth, so as to receive the pipe D, which is about two and a.half inches in diameter, and located one inch above the bottom of thebox. The box A is covered with a suitable lid, E, which may be removedat pleasure forcleansing. The pip-e D is made in sections, so thatitslength muy be readily adapted to the required distance,'and the end onthe outside of the house is provided with n. wire-screen cap, G, toprevent it from being choked. The box A andpipeD should be made of castiron. The lid E of thebo'x A may be made level with the hearth, insteadof being elevated, and in that case the vents und demper-may be placedin the lid. H is a line :to repre- -sent the top of the hearth. J is aline representing the bottom of the hearth. The hearth is supposed tobel made of brick three inches thick. K represents the grate of thefireplace.

What I claim as my invention, and desire to secure by Letters Patent,is- The arrangement and construction of the box A, damper C, lid E, andpipe D, when combined as herein described and for the purposes setforth.
